Aluminium metal matrix composites (AMCs) reinforced with hard ceramics are highly demanded composites which have the potential of fulfilling the current demands of advanced industrial applications due to its light weight and high strength properties. This paper attempts to review the various properties (microstructural, physical, mechanical and tribological) of the Al-ZrO₂ reinforced composites. The microstructural results obtained by the many researchers showed the uniform distribution of the reinforcement particles within the matrix and good bonding between them. The physical and mechanical behaviour of the composites enhances with the increment in the weight content of the ZrO₂ particles. It has been observed from the literature that the tribological properties also improved with the addition of the ZrO₂ particles within the Al matrix.
